为了寻找温热的星系间介质（WHIM），计划发射一颗小卫星使命DIOS（弥散星系间氧探测器），并研制了一台特殊设计的四反射X射线望远镜（FXT），作为最适合的光学系统，它具有宽视场和大有效面积。根据FXT光学系统的设计和反射镜的制作方法，制作了由10个四级反射镜组成的四象限模型。我们描述了该系统的预期和实测性能。
To search for warm-hot intergalactic medium (WHIM), a small satellite mission DIOS (Diffuse Intergalactic Oxygen Surveyer ) is planned and a specially designed four-reflection X-ray telescope (FXT) has been developed as the best fit optics to have a wide field of view and a large effective area. Based on the design of optics and mirror fabrication method developed for FXT, we made the quadrant model with ten nested four-stage mirrors. We describe the expected and the measured performance of this system.
